7.9. Setting an additional heater (Optional E-heater)
For the HMI range:
Once you have entered the “Optional elec. heater” function,
you can activate or deactivate any additional electric heater.
This heater may be single-stage or dual-stage (in the case
of a dual-stage model, you can decide whether or not to
use both stages by specifying the number of heaters in the
first parameter). You can also set the outdoor temperature
threshold below which it will be activated in place of the
heat pump. WARNING: it is compulsory to select “Logic
1”. Press the top right button to save the data entered.
NOTES:
1. When this function is activated, it permits the activation of the supplementary heaters (via a 230V ~
50Hz signal to the "KM1" and "KM2" terminals; in the case of a single heater, use the "KM1" terminals
only) if the outside temperature falls below the value specified in the “Elec. heater T." parameter or if
“Emergency mode” is activated.
2. The supplementary water probe must be installed downstream of the electric heater (for more infor-
mation, refer to the installation manual).
3. If this function is used, no additional heat source can be enabled (Additional heat source).
4. The electric heater must be installed downstream of the 3-way valve (terminal side of the system).
5. The DHW request will be met by the electric heater in the compatible Aermec accessory tank
, where-
as the system request will be met by the electric heaters.
6. The electric heaters for the system, and the electric heater in the DHW tank available as an Aermec
accessory, will never be activated simultaneously.
7. If the relative function is activated (paragraph 8.3), the value of these parameters will be stored in the
memory and automatically reset after any possible voltage failure.
For the BHP range:
Once you have entered the “Optional elec. heater” function, you can activate or deactivate the electric heaters in-
stalled on the indoor unit, as per the following configurations:
• BHP060W and BHP060F = 1.5kW + 1.5kW
• BHP100W and BHP100F = 3.0kW + 3.0kW
The “Elec. heater T.“ parameter is used to set the outside temperature threshold below which the heaters should be
activated in place of the heat pump. WARNING: it is compulsory to select “Logic 1”. Press the top right button to
save the data entered.
NOTES:
1. Once this function has been activated, it will give consent for the enabling of the electric heaters if
the outside temperature falls below the value specified in the “Elec. heater T.“ parameter or if “Emer-
gency mode” is activated.
2. If this function is used, no additional heat source can be enabled (Additional heat source).
3. The DHW request will be met by the electric heater in the compatible Aermec accessory tank
, where-
as the system request will be met by the electric heaters.
4. The electric heaters for the system, and the electric heater in the DHW tank available as an Aermec
accessory, will never be activated simultaneously.
5. If the relative function is activated (paragraph 8.3), the value of these parameters will be stored in the
memory and automatically reset after any possible voltage failure.
